ebay or any large hobby shop should have a good selection of old mack models I think all the 1/25 and 1/24 scale mack models (besides the superliners) are temporary discontinued. However they are still selling from people that buy them in large amounts and mark them up http://www.stsmodeltrucks.com/ has all the needed aftermarket parts for your mack truck models Trent

it does sound like an air sucking issue. If it starts and runs then quits that means that it can supply the engine with fuel untill to much air enters and the prime is lost. if all the lines are good and not craking etc.. look in the fuel tanks for dirt or rust etc... I have heard that the pick up tubes at the top of old fuel tanks rust and may allow air to enter the lines. wile there, check to see if the pick up tupe is clogged. If you removed the hand primer its likely the fuel drained all the way back to the tanks. you may need to force air into the tank and help the fuel get into the lines again to start it? after it starts crack the injectors one at a time and wait for the chugging to stop then tighten them.

I thought mack still had the tan in a spray can? I just bought the interior grey spray last month Trent

Im 26 and altho I have never smoked a joint, or abused any type of Drug...EVER! alot of my friends that I still have today , took drugs. I have freinds that smoked pot as young as 10 and even lost a few long time friends from cocaine OD back in my high school years. Drugs have been around for 1,000s of years but the rate at wich people fall victim is crazy I know people say pot is the gateway drug. but I say the problems all start in your head. It seems that the people that get hooked have other issues in there life and find drugs as an easy escape to there problems. most of the kids in my HS only did drugs with other users. Everyone would meet after school for a joint. or all meet up and look for someone with pot. It was pretty sad my 2nd year in HS when most of the students only wanted to smoke a joint with the older kids thinking it was cool. I have been out of HS for some time now and many of my friends that did drugs now sencerly regret some of the things they did. I have lost a few great friends because they refused to stop abusing. Its sad when I think back of how we were back in grade school and how they chouse a drug over a long time friend. some times people will wake up and relize what they have done to you and themselves. I always give someone a 2nd chance. However I honestly dont have an issue with people wanting to smok a joint or social drinking, poping a pain killer from time to time etc.. to relax. but I do have isser how so many kids today get into drugs soearly, get hooked during HS years and later move onto hard core drugs. I think the main reason I never got into drugs was because I was too busy working on my stuff..go cart, riding lawn mower, alwasy had a wrench in my hand or an idea in my head. I thank my mom for letting me roam the neighborhood looking for side jobs with friends, allowing me to learn things by trial and error. If more parents would let/ make kids stay out side I think many of them would steer clear of drugs. Trent

one thing I have noticed with drivers is that if they have not driven a mack before, is they will have difficult time learning how to shift the gear box . When I was working full time driving dump trucks I had to give a few new guys that were 10 + years older than me a road test in a R model. With the 5 speeds, they could never get the timing right and were depressing the clutch all the way untill the clutch break was causing them more issues. It also seams as if the new breed of drivers all come from some large OTR out fit i.e swith.jb etc..and when they found that the life of the OTR was not what its cracked up to be they look for local jobs. these are the worst type to get as they likely took a test with an automatic truck to get there CDL then sent directly to a throw away garbage freightliner where they "learned" to just bang the gears into position and not wait for the rpms to drop. at my current job we have 6 truck drivers and I can honestly say that only 3 of them, including myself, know how the trucks drive train functions. most cant even figure how to "pre select" gear with the splitter... I could go on and on about new drivers stories but its something we all have heard before.

Rob, my advice is to grow some eyes in the back of your head!!

I think your right HK trucking besides the range selctor transmissions i.e T200 sieres that had the syncro pack for the range selection. I dont know of a synchromesh trans that is MACK mfg. alot of the trucks mfgs made over seas do have car transmissions i.e syncromesh ....LOL

Larry. I am Suprised he dosent stop over hear to pick on us mack guys...LOL

I looked into this last week. the electric motor looks as if it bolts directly to the firewall where the air motor is. I think the wiper motor , wireing and control switch is all you will need to convert it over. on a side note I decided to stay with the air motor. The air valve was causing problems with the wiper control and speed. bought a new valve for $60. and all is fine again

if you are hooked to a trailer and pull the yellow one I think the red pops out also. when the blue is pulled the yellow and red stay in.. I move the truck every day and never stop to think about it but I think thats how mine works

I have driven a V8 Detroit in a prevost bus and the twin pyros said the EGTs heated up real quick to 1150 and held it there My companys 550 cat will climb to 900 and hold for a long time before it gets to 1100. I havent found a hill east of Airizona that I have to worry about EGT,oil,trans etc.. temps If im out in CA on a hot day pulling hills on I-5 I have had to pulll over and let my EGT, trans, engine oil and water temps cool. guages can save you from a real bad day!!! All the diffrent engines work the same (basicly) but they will all have a diffrent over heating points of the componets. maxidynes flow alot of fuel at low rpms, when that turbo boost falls off. things will get hot [quickattachmentid=655]

blue is tractor park yellow is tractor and trailer park red is trailer park

900 deg is 100% fine. where is the EGT probe. most are after the turbo where temps are a little lower than what the cyl temps are at.. make shure the "new" pyro guage is calabrated to the specific placement of the probe. I start to worry around 1100-1150 and dont let it stay at 1200 for very long. At WOT the lower the rpms the higher the EGT temps will get. down shift or lift up a little. more fuel will make EGT temps rise if the turbo can not put out the needed air to keep things in check.. more air alows the extra fuel to be burned off. you can get more power with added fuel but you will reach a point that the excess fuel will just cause high EGTs. I see 1000 deg temps with my truck and it gets a little higher if the boost starts to fall off lugging it with a good load holding me back.

the signs are posted all the way out to the west coast . most signs say "excessive engine brake use is not allowed" or something along those words.

kINDA LIKE A POOR MANS WATER INJECTION I can see how a mist of water is safe and actuly good for the engine but you know there is going to be a day you drive through that huge puddle and a massive amout of water could get sucked into the tube? that can cause an expinceve repair if it gets to the engine.

I always wondered how good or bad they were when it was raining out? looks like it could suck in lots of water even with the gills on the sides? I know they were used alot Down under because of the dust. Wonder if the ram air effect helps power at Hwy speeds? I like the looks of them. trent

hope this helps Trent

I have no mechinacal info on how the 6cyl jake can be improved but I have driven a few macks with the Jake brake and they all performed poor in my opinion. At best they would slow the rpms but never could hold back a meduim loaded truck. I think the reson is because of the smaller 673,676, 675 etc... displacement engines??. we have an E9 at the yard with a jake and it stops much better than the small 6 cyl. Trent

I have driven a few superliners with electric powered pass window. If I remember correctly it was a black box mounted to the door that housed a motor and gear for the window regulater. It was ugly looking and blocked some needed space in the passenger aera. Im not shure if you can still get these motors. air would be great but Im thinking you would have to "re-invent the wheel" so to speak

any good truck stop or chrome shop will have the spring hangers. some will just have a coiled rod that will relive some stress and then ther are the expencive ones that will have a spring inside the tube to help keep flaps on.. no ,matter how much the flap holder bends. the flaps can still tear off easy...sound to me like all you need to do is adjust your mirrors!!!! LOL... Just kidding! the dogs can be found on ebay. I think the dog you want is the ones used on the ash trays? somone here will know for shure about this .. Trent

thanks for the pics. some great looking trucks in those photos. please scan some more when you get time. Im shure we all would love to see more !!! Trent

wonder why the alum panels and doors never cought on with mack? Steel is stronger but if weight is a big issue an alum cab could save alot. The later aluminized cabs seem to hold up pretty well.

what was the issue between the G model mack and KW claiming that it looked to simmilar to there cabover?

a frind of mine with a BCR has the thermodyne emblems. first time I have seen them on a R model
